Hydroxylamine reacts with diphenylphosphinic chloride (1) in benzene (or aqueous dioxan) to give O-(diphenylphosphinyl)hydroxylamine (3) and not the N-phosphinyl compound (2) as was previously thought. Di-p-tolyl-,bis-p-methoxphenyl-, and phenyl-p-methoxphenyl-phosphinic chlorides are similarly attacked by the oxygen of hydroxylamine. The structures of the phosphinylhydroxylamines can be inferred from
羟胺与二苯次膦酰氯(1)在苯(或二恶烷水溶液)中反应生成O-(二苯次膦酰基)羟胺(3),而不是N-次膦酰基化合物(2)。二p甲苯基- ,双- p -methoxphenyl-,和苯基- p -methoxphenyl次膦氯化物类似地通过羟胺的氧气攻击。膦酰基羟胺的结构可以从它们的化学反应中推论出来。特别地,它们与丙酮缩合,得到与从次膦酰氯和丙酮肟获得的那些相同的次膦酰基丙酮肟(8)。就像Ø - sulphonylhydroxylamines,Ö-(二苯基膦基)羟基胺分别与三苯基膦和二甲基硫醚形成氨基phosph盐和氨基s盐。
